Definition
Hawaiite is volcanic rock that resembles basalt. It is an olivine basalt with intermediate composition between alkali olivine and mugearite
Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt

Formation
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.
Epidosite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

More about Hawaiite and Epidosite
Here you can know more about Hawaiite and Epidosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hawaiite and Epidosite consists of mineral content and compound content. The mineral content of Hawaiite includes Olivine, Plagioclase, Pyroxene and mineral content of Epidosite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Hawaiite vs Epidosite, the texture, color and appearance plays an important role in determining the type of rock. Hawaiite is available in black, brown, light to dark grey colors whereas, Epidosite is available in black, brown, light to dark grey colors. Appearance of Hawaiite is Dull and Soft and that of Epidosite is Dull and Soft. Properties of rock is another aspect for Hawaiite vs Epidosite. Hardness of Hawaiite and Epidosite is 6. The types of Hawaiite are Volcanic rock whereas types of Epidosite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Hawaiite is while that of Epidosite is white to grey. The specific heat capacity of Hawaiite is 0.84 kJ/Kg K and that of Epidosite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Hawaiite is heat resistant, pressure resistant, wear resistant whereas Epidosite is heat resistant, pressure resistant, wear resistant.
